PHP Sending HTML form data to an Email

In this article, we are going to learn how to collect the HTML form data and send to an email using PHP programming language.

In almost any web application, it is a common requirement to have a form. Gathering form data and deliver to email inbox is a very convenient way and PHP makes this process more dynamic as using this we can handle hundreds of responses per day. This process is based on the client server architecture. The HTML form is on the client side, when user hits on the submit button, the data will be sent to the URL of the page specified on form action.

Here, we have created two pages - form.php and sendmail.php. The "form.php" page will collects the data entered by the user and the file "sendmail.php" will collect them and send to an email.

form.php

The given form contains the following fields: to, from, subject and message.

<html>
<head>
<title>Sending form data to an Email</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" />
</head>
<body>
<div class="wrapper" style="width: 35%; margin: 0 auto;">
<form name="mailinfo" method="post" action="sendmail.php" class="form-signin">
<input type="text" name="to" size="40" class="form-control" placeholder="To:" />
<br/>
<input type="text" name="from" size="40" class="form-control"  placeholder="From:" />
<br/>
<input type="text" name="subject" size="40" class="form-control"  placeholder="Subject:" />
<br/>
<textarea cols="50" rows="5" name="message" class="form-control" placeholder="Enter your message">
</textarea>
<br/><br/>
<input class="btn btn-small btn-primary" type="Submit" value="Send"/>
</form>
</div>	
</body>
</html>

In the above file, we get the inputs from user. When the user click on the send button, "sendmail.php" page is loaded. On this page, we collect all the post data in variables, then we use the PHP mail function to send mail. The mail() function returns a value of 'True' if it is successful and 'False' if it fails.

sendmail.php

<html>
<head>
<title>Sending form data to an Email</title>
</head>
<body>
<?php
$to = $_POST['to'];
$from = $_POST['from'];
$subject = $_POST['subject'];
$message = $_POST['message'];
$headers = 'From: '.$from.'\r\n';
$mailsent = mail($to, $subject, $message, $headers);
if($mailsent) {
echo 'Mail has been sent<br/><br/>';
echo '<b>To: </b>'.$to.'<br/>';
echo '<b>From: </b>'.$from.'<br/>';
echo '<b>Subject: </b>'.$subject.'<br/>';
echo '<b>Message: </b>'.$message.'<br/>';
} else {
echo 'Error in the message.';
}
?>
</body>
</html>
